ask for the chat id, do not offer session names

it offered a choice between platform-13 and platform-94. those are the
platform's own bookkeeping — the owner has never seen one, they change when
a session restarts, and from outside two of them look identical. offering
that choice asks somebody to guess.

what they can actually get is the id in the address bar: open the chat you
mean and it is in the URL after /chat/. ask for that, in those words, and
take it as free text.
